The power knowledge graph is able to realize semantic-based power knowledge searching. After the constructing of the current power knowledge graph, the power data in graphs are not often updated. With the increasing of power project data and the change of existing power project progress, it is necessary to update the power project knowledge graph. In order to ensure the effective of the power project knowledge graph, the old power knowledge graph should be updated using the new power data. The method, which is used for updating the current power knowledge graph using Neo4j graph database through Cypher, was proposed in this paper. The proposed power project knowledge graph updating method is not only for per-data, but also effective for batch data. This proposed method can deal with different demand scenarios, expand the knowledge graph of power technology and ensure the accuracy of the content of the knowledge graph.
